Title: Semiconductor device and manufacture thereof
Inventor: FUKUDA KOJI
IPC: H01L21/321
Filed: 1991-07-04
Abstract: PURPOSE:To prevent the generation of cracks by application of internal stress to the final insulating film on the overlapped part of a Cu plated layer, which constitutes a bump, and the final insulating film. CONSTITUTION:A second insulating film 5 is formed on the aperture part of the final insulating film 4 located on the bonding part 3 provided through the intermediary of a first insulating film 2 on a semiconductor substrate 1, a plurality of bump-forming parts of the prescribed size are formed. On these divided parts, Cu-plated layers 8 are formed on the respective divided parts through the intermediary of a Cr layer 6 and a Cu layer 7, and a solder layer 9 is formed covering the Cu-plated layers 8 entirely. Accordingly, the stress added to the overlapped part of the individual Cu-plated layer and the final insulating film becomes very small by dividing the bump part, and as a result, the generation of cracks on the final insulating film can be prevented.

Title: Absorption water chiller and heater
Inventor: KONDO MASAYUKI
IPC: F25B43/04
Filed: 1987-07-01
Abstract: PURPOSE: To simplify the structure by providing a U-shaped pipe of a different cross-sectional area between a gas storage chamber and the container for an evaporator and an absorber thereby using a hydrogen transmission unit commonly at the time of cooling and heating. CONSTITUTION: At the time of heating operation, pressure in a gas storage chamber 3 increases because heated steam flows in through U-shaped pipes 23, 24 and solution flows down through a pipe 14. Consequently, solution in the pipes 14, 15 higher than the opening of a pipe 19 passes through a gas-liquid separator 6 and the pipe 19 and returns back to the lower section of the container for an evaporator and an absorber 4. A steam layer thereby prevails in the U-shaped pipes 23, 24. Hydrogen generated in an absorption cold/hot water unit by the steam layer is discharged from a hydrogen transmission unit 10 in the gas storage chamber 3. At the time of cooling, the solution drips from a concentrated solution ascending pipe 18 down to an absorber 2 and absorbs steam from an evaporator 1 before dropping to the lower section of the absorber 2.  The dropped solution flows from a liquid pan 22 to the pipe 23 up to a level indicating the pressure difference between the gas storage chamber 3 and the lower section of the absorber 2 thus sustaining the pressure difference between them.

Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To suppress high ray loading to an entire scanning region and the bleeding phenomenon of spectrum beams and to accurately judge an image by changing the composition of spectrum and light intensity every time when the application point of a laser beam is switched. SOLUTION: By occasionally suspending the incorporation of a spectrum constituent into a light path while repeating the deflection operation of the microscope light path and the entire application of rays, laser beam can be applied only to the selected portion of an image surface. A laser beam with increased intensity is applied only to the sample site for judging an image, and a sample 16 is protected. Laser beams enter a scanning device 8 of a ray deflection unit 9 through a plurality of optical couples 5 and a filter 6. Further, a laser beam enters the light path of a microscope 15 and is directed toward the sample 16. The reflection and radiation light of the sample 16 returns to the ray deflection unit 9 and reaches an image-forming lens 21, where the light is branched into a detection pipeline 22 and is directed toward a photomultiplier 23.  For reducing a ray load and improving quality for judging an image, the incorporation of a spectrum is suspended or the spectrum is additionally incorporated while an object 34 is being scanned.

Abstract: PROBLEM TO BE SOLVED: To provide a ringing choke converter(RCC) which is highly efficient at operation with small output power (at light load). SOLUTION: This ringing choke converter operates with only the first base resistor 8 at operation with small out power by setting the optimum time when a transistor 9 is turned on by the time constants of a resistor 12 and a capacitor 10, and when the output power becomes large and the on period extends, the transistor 9 is turned on, and the current where a current flowing to a second base resistor 13 is added to the current flowing to the first base resistor 8 is supplied, as a drive current, to the base of a transistor 3. Hereby, drive loss can be reduced at the time of small output power, and it becomes possible to operate the transistor 3 under optimum drive condition, and besides it becomes possible to drive the transistor 3 enough even at the time of maximum output power.

Title: Power supply circuit for both chargeable apparatus and ac apparatus
Inventor: SAKAGAMI MASAAKI
IPC: H02J7/00
Filed: 1989-06-26
Abstract: PURPOSE:To eliminate abrupt variation of output current and to supply stable power, in a power source for charging a battery and driving a load, by providing a means for detecting load drive voltage and an output control means for varying output current from the power supply continuously. CONSTITUTION:Upon throw in of AC voltage V1, a switching transistor Q1 functions to induce AC pulse voltage in the secondary winding of a transformer T. The induced voltage is rectified through a diode D1 and fed, as an output current Iout, to a battery B. When a switch Sw is turned ON, another motor to be charged by the battery is also driven. When the battery voltage VB exceeds over a predetermined level VB1, a transistor Q2 is turned ON to reduce the voltage to be induced in the transformer winding L1 in an oscillation base circuit and thereby output Iout from a switching power supply decreases gradually to go to zero when the battery voltage reaches to VB2. Since the output lout does not go to zero instantaneously even if the battery voltage exceeds over the predetermined level VB1, motor drive voltage V2 does not fluctuate abruptly.

Abstract: PURPOSE:To visualize a color image and to obtain a color recorded image, by charging only the parts of a drum corresponding to the filter parts having a relation of complementary color to a toner to a polarity opposite that of to an electrostatic latent image, and bringing the toner into contact with an electrostatic latent image. CONSTITUTION:A drum 1 is rotated in the direction A in the drak, and its circumference charged with a charger 2 passes by stripe filters 3. At that time, positive charge remains only on the parts facing a blue filter and a green filter, and charge on the other parts is erased. On the other hand, on a cyan donor roller 4A a cyan toner corresponding to a red filter is not attracted to the drum 1. On the contrary, yellow and magenta toners are arranged in a stripe on a magenta donor roller 5A or a yellow doner roller 6A, etc. to regenerate a red color on the whole. Other record developing devices are operated likewise, permitting a full color record image to be formed by combining each color of cyan, magenta, and yellow.
